Unless I misunderstand what you're asking for; you can do the assignment multiple times with different values:
$text = sub { <<EOT; Dear $person, I know that this text is $adjective. But I wish it could be... EOT }; my @subs=('Mom:not interpolates', 'Dad:maybe interpolated', 'Sis:who knows'); foreach (@subs){ local ($person,$adjevtive)=split ':',$_; print &$text; }
My technique will also work for your number example (with everything stored as a function). However it look slightly ugly:
$n = sub {1}; $m = sub {&$n*2}; $o = sub {&$m*2}; $s = sub {&$n." ".&$m." ".&$o."\n"}; print &$s; $n = sub {2}; print &$s;
